[wsf-c-dev] Amazon web services solution using wsclient

[Damitha Kumarage]

Hi,

I would like to discuss the command line application solution I'm 
working on and get your feed back. I would like to name the tool as 
easy_buy_amazon.
It is executed with a set of command line options. There is a resource 
directory containing a pre-defined set of xml files designed for each 
possible transaction with the EWS(Ecommerce Web Service). when user 
execute the easy_buy_amazon with the options, the application scripts 
internally use sed(or perl) to modify these custom xml payload files 
with the user given options.

The operation invoked on the EWS web service falles into three categories

Search
Lookup
Cart

Operations under each category are

Lookup Operations:

    * |BrowseNodeLookup|
    * |CustomerContentLookup|
    * |ItemLookup|
    * |ListLookup|
    * |SellerLookup|
    * |SellerListingLookup|
    * |SimilarityLookup|
    * |TransactionLookup|

Search Operations:

    * |CustomerContentSearch|
    * |ItemSearch|
    * |ListSearch|
    * |SellerListingSearch|

Shopping cart Operations:

    * |CartAdd|
    * |CartClear|
    * |CartCreate|
    * |CartGet|
    * |CartModify|

--easy_buy_amazon --help
would show the user the common properties and all these avaiable operations.
The common properties are
subscription_id
associate tag
validate

easy_by_amazon --help CartAdd would show all operation specific properties.

An example of use would be

easy_by_amazon --subscription_id xxxxxxxx --op=ItemSearch 
--author=Stephen King --locale=uk --total=50 > result

would return get the list of top 50 books by Stephen King on the 
Amazon.co.uk site. The resulting xml file is redirected to a file called 
result.

Additionally a small program called amazon_result(which is internally 
using axiom to parse the result xml file) could be used to parse the 
nodes and display the result in plain text.

easy_by_amazon --subscription_id xxxxxxxx --op=item_search 
--author=Stephen King --locale=uk --total=50 > result | amazon_result

thanks
